WILLIAM B. FENN, OF MERIDEN, CONNEGTICUT, ASSTGNOR TO FOSTER, MERBIAM &CO., OF' SAME PLACE' PLANEr EECIFICATION forming part of Letters PtentNo. 291,178, dated January 1, 1884.

Application filed September 3.1883. (No model.)

erence being had to the accompanying drawp ings, forming a part of thisspecfication, in eX- plaining its nature, in which`- Figure l is aperspective View of a plane containing my invention. Fig. 2 is alongitudinal Vertical section. Fig. 3 is a cross-seetion on the line x xof Fig. 2. f Fig. 4 is a Vertical section on the line y y of Fig. 2.Fig. 5 rep'resents a modification in construction hereinafter described.

The invention relates to various details of Construction, all of whichare hereinafter fully described.

Referring to the d'awings, A represents the stock of the plane. It ismade of metal, has the vertical side extensions or fianges, a, thehandles a a and the knife-opening (9 Cast with the stock, or Securedthereto by rivets or in any other desirable way, is the triangularshapedblock B. This block is nar'rower than the plane-stock, and is arrangedimmediately back of the knife-opening, and there is a recess or spacebetween its vertical sides and the inner sides of the extension orfiange a.. Its upper surface is inclined, preferably, parallel with theincline (6 of the knife-opening. To this upper surface of the block isfastened by screws a or otherwise secured, a plate, a which is of thesame inclination as the surface of the block, and which extends beyondit on each side to furnish supports or ways for the earriage C, whichholds the plane iron or knife.

Instead of making the plate (6 separate and attaching it to the block B,it may be made integral therewith, if desired. The location of thisblock and plate in relation to the knifeopening and to the side flanges,a, of the plane is well shown in Fig. 3.

Extending up'wardly and baekwardly from the block B is the threadedspindle or screw, b, by which, in connection' with the deviceshereinafter described, the carriage, and there fore the plane irons orknives, is adjusted Vertically.

The carriage O has the flat upper surface or bed c, upon which the planeirons or kniyes D rest, the flat under portion, c', which slides in thedownwardly-projecting portions of the carriage grooves or recesses whichfit the outer edges of the plate a?, It is of course innnaterial as tohow these grooves or recesse's are formed. They may be made in castingthe block, or they may be planed out; and it is also inimaterial as totheir shape andthe shape of the edges of the plate in cross-section, asthis shape may be square, or partially rounded, or inclined upon theunder. edge. The

earriage C` also has the downwardly-extending lug or bracket 0 which hasthe projections c?, that straddle the portion .of the nut ct. This nuthas a thread, 0 which fits the thread on the inclined screw or spindleb. The shoulders 0 .0 at the lowerend of the nut, fasten .the

projeetions c* of the carriage securely toithe nut, so that upon therevolution of the nutthe carriage is raised or lowered.

It will be observed that the nnt is so located in relation to the backhandle of the plane that it can be easily revolved without removing thehand from the handle, so that the plane irons or knives may be adjustedwhile the plane is being moved. The plane-irons are Secured to thisblock by means of the headed screw-spindle'E,which screws into thecarriage, and of course may be adjnsted in and out in relation thereto,and which passes through the hole e in the plane-irons and the key F,which has forned in its under surface in any desirable way theprojections f, which shut under the head of the screw. The under 9surface, and especially the lower edge of the key, bears upon the upperplane-iron, and the screw f' in its upper end hears upon the upperplane-iron, throws the lower portion of the key rigidly against thelower portion of the plane-iron, and being held to the carriage by theheaded spindle or screw E, the plane knives or irons are rigidlyfastened to the earriage. The plane-irons are seeured to each other bythe coupling-serew d, and a hole, d', is made in the earriage to receivethe head of this screw.

The advantages of this invention are siniplieity and eheapness ofConstruction and ease of adjustnent of the irons.

It will be observed that the threaded spindle or stem b need notnecessarily be seeured to the block B, as it can be i'astened to anyother part of the stock or body of the plane provided it is arranged toproject diagonally upward, as shown.

It will also be seen that by making the headed screw E adjustable in theearriage plane-irons of Varying thickness may be used, and that a tightfit between the key-piece, plane-irons, and earriage may be obtained,which is desirable, as it prevents chips, dust, and shavings fronigetting between the various parts, and also holds the plane-irons moresecurely in place.

In Fig. 5 I show the nut secured by the body of the plane or block B,instead of to the knifecarriagc C; and I prefer to secure the nut inplace by tapping a hole in the block or body of the plane and forning aprojeetion on the end of the nut,which shall tightly fit the hole whendriven therein. The serew-spindle will, in this eonstruction, take theplace of the nut c in relation to the carriage C, and the screw willenter the stationary nut or, in other words, in this modification thenut is stationary and the serew-spindle movable with the earriage.

Of course thcinvention can be used in planes having wooden bodies, orbodies having wooden bottons and metal frames, if desired.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. Aplane bed or stock havingthe block B, cast upon or fastened to the inside thereof, of less widththan the body of the plane,and provided with ways or guides for thesupport of a movable plane knife or iron supporting earriage formedthereon by means of the projections a?, all substantially as and for thepnr poses described.

2. The combinatio of the plane bed or stop A, the block B, fast-ened orseeurcd thereto narrower than the plane-stock, and having the projectingguides ((7, with a movable or knife-supporting carriage, C, having theoutwardly-projecting portions or wings c' which lap under the undersurface of the guides, all substantially as and for the purposesdescribed.

3. 'l`he combination, in a plane, of the stock or bed A, the block B,fastened thereto as described, and of less width than the body of theplane, provided with the ways or guides a which project therefrom, asspecified, the threaded spindle or screw b, the plane knife or ironsupport-ing carriage C, having the pro jecting portions c'-', which lapupon the under surface of the guides or fianges (i, and the nut c,secured to said earriage, as described, all substantially as and for thepurposes set forth.

4. The combination, in a plane, of the tlrcaded spindlc or stem fixed inthe body ot' the plane, the plane iron or knife supporting carriage G,having the projections c*, which straddle the nut e the said nut &whichworks upon the threaded stern, all substantially as and for the purposesdescribed.

5. The plane knife or iron supporting carriage C, having the bracket orprojccton 0 whose projeeting ends straddle the grooved or reeessed nut cbetween the shoulders c* c. all substantially as and 1" or thepurposesdescribed.

G. The conibination of the adjustable screw or lug E, having in thenovable earriage C the plane iron or irons D, and the key F, having theundereut recess in its under surface, adapted to receive the head of thescrew or lug, and the looking-screw f@ all substantially as and i'or thepurposes described.
